UTF-8 all the way through 14 answers

MySql database uses utf-8 encoding and data are stored correctly.I use set_name utf8 query to make sure the data called are utf-8 encoded.all variables from database works fine as long as the header charset is utf-8,but the static html characters do not work properly.When i set header charset to ISO-8859-9 variables are displayed differenly while html characters work ok.can anyone help me? Utf8 encoding: http://oi48.tinypic.com/289kje1.jpg html tags have problem displaying values.but php data(green ones e.g. ağişler) that come from database is ok.ISO encoding http://oi50.tinypic.com/287n2ph.jpg this time the html is ok but php data are displayed wrong.

<?php
    header('Content-Type: text/html; charset=ISO-8859-9');
    ?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head><title>noname</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

</div>

You can try explicitly adding content type at the top of your file as below

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

and remove the below from your code..

header('Content-Type: text/html; charset=ISO-8859-9');

Update:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<?php echo "for example Ş and İ "; ?>   
</body>
</html>

The above code gives me the below output:

So data from the database works if you tell the browser to interpret it as UTF-8, that means that data is UTF-8 encoded. The HTML code works if you tell the browser to interpret it as ISO-8859, that means the HTML is encoded in ISO-8859.

So you have a document with mixed encodings. Bring those two together. Save your source code files as UTF-8 and tell the browser to interpret it as UTF-8, or get your data from the database in ISO-8859 and tell the browser to interpret it thusly.
